ANDREW KOESCHE, OF CHICAGO, ILLINOIS.

ELECTRIC PUMP-RE GULATOR.

Specification of Letters Patent. Application filed September 13, 1907; Serial No. 392,621.

Patented March 10, 1908.

To all whom it may concern:

Be it known that 1, ANDREW KoEsoHE, a citizen of the United States, residing at Chi- L cago, in the county of Cook and State of Illi- 1101s, have invented new and useful Improv evolume o water in a tank.

In the accompanying drawings 1' have illustrated the invention as ada ted for connection with a closed water tan to be operated by pressure in the tank.

Figure 1 is a plan view, partly in section",

showing the parts in closed position in full lines and in open position in broken lines. Fig. 2 is a sectional view on the line 22 of Fig. 1. Fig. 3 is a sectional view on the line In the adaptation of the invention shown in the drawings, a cylinder 4 is mounted on a suitable insulating base 5 and connected by a pipe 6 with a closed water tank. A piston 7 is carried by a stem 8 within the cylinder/1 and this stem is guided in a bracket 9 on the base and has its upper end provided with an eye 10. A lever 11 ,passes through the eye 10 and is fulcrumed at one end 12 on the base and carries a weight 13 at its other end. p

I have shown a double pole switch in which there are two stationary contacts 14 mounted on the base and two movable contacts 15, the former being in the familiar form of spring contacts and the latter in the form of blades to engage the spring contacts. The stationary contacts 14 are connected by wires 14 with binding posts 16 to which the line wires 16 are connected. The movable contact blades 15 are on levers 17 fulcrurned at 17 on the base and connected at their fulcrums by wires 15 with binding posts 18 to which the motor wires 18 are connected.

Angle levers 19 are fulcrume'd at 20 on the bracket 9 and have arms 19, 19" The arms 19 carry fiber blocks 21 and springs 22 are connected to posts 23 on said blocks and posts 24 on the levers 17. The arms 19 are engaged by a tripper on the stem 8, this trip per comprising a bracket 25 fastened in ad'- justable position on the stem and two pairs of. fingers '26 spaced apart and adjustably fastened in sockets 26 in the bracket (Fig. 3).

pair of fingers 26.

break the contacts.

The free end of each arm 19 projects into and operates freely in the space between each 21 is provided with a projection 21 which is arranged to engage a lug 27 on the underside of themovable contact lever 17 (Fig. 2) and cushioned stops 28 are located on the base to limit the movement in one direction of the movable contacts.

In practice the center of the fulcrum of each angle lever is located out of alinement with the center of the fulcrum of its movable contact lever and preferably in a line between the center of the fulcrum of the mov- 'able contact lever and the stationary conswing the angle levers on their fulcrums.

When the posts 23 are moved inward past the center line of the fulcrums 17" the springs 22 will swing the levers 17 against the stops 28 thereby breaking the contacts as indicated in broken lines in Fig. 1. If for any reason the springs fail to swing the levers 17 at the proper time the projections 21 will engage the lugs 27 and swing said levers to When the pressure under the piston diminishes and the weight "13 causes the piston to descend the tripper will swing the angle levers'in the opposite direction and cause the levers 17 to swing from the position indicated in broken lines in Fig. 1 to the position shown in full lines.

The invention is simple in construction and accurate in'its operation. The parts can be readily adjusted to eflect the operation of the switches at any desired pressure and to insure the simultaneousoperation of the switches. While I have stated that the pipe 6 is connected to a tank it is obvious that the regulator can be otherwise applied and operated by air, gas, steam or water with equally satisfactory results. It will Each of the fiber blocks 1 be observed that the contacts'are widely and it can be actuated by other means in subable contact, a lever carryin said movable stantially the same manner and with equivcontact, a two arm angle ever pivotally alent results.

What I claim and desire to secure by Letters Patent is:

1. The combination of a movable tripper, an electric switch comprising a stationary contact and a movable contact, a two arm angle lever having one arm engaged with the tripper, a lever pivoted independently of said angle lever and carrying said movable 1 l I l 1 l i I contact and extending in the same general direction from its pivot as the other arm of said angle lever and in the several positions thereof, the fulcrum center of said angle lever being located out of line with the fulcrum center of the contact lever and the stationary contact, and a spring connected to said other arm of the angle lever and to said contact lever.

2. The combination of a movable tripper, an electric switch comprising a stationary contact and a movable contact, a lever carrying said movable contact, a two arm angle lever having one arm engaged with the tripper, a spring connected to the other arm of the angle lever and to the movable contact lever, a lug on said movable contact lever, and a projection on the angle lever to engage said lug.

3. The combination of an electric switch comprising a stationary contact and a movmounted independent of said contact lever, the fulcrum center of said angle lever being out of line with the fulcrum center of the contact lever and the stationary contact, a

a piston in said cylinder, a stem carrying said I piston, a weighted lever engaged with the stem, a tripper comprising a bracket on the stem, a pair of arms spaced apart and pro j ecting from the bracket on each side thereof, a pair of electric switches each comprising a stationary contact and a movable contact, a lever carrying the movable contact, a pair of two arm angle levers each having one arm' projecting into the space between a pair of fingers, and springs connected to the movable contact levers and to the other arms of the angle levers.
